Beryllium-aluminum alloy an alloy that consists of 62% beryllium and 38% aluminum, by weight, corresponding approximately to an empirical formula of Be 2 Al. It was first developed in the 1960s by the Lockheed Missiles and Space Company, who called it Lockalloy, [1] [2] and used as a structural metal in the aerospace industry because of its high specific strength [3] and stiffness.

For gases, departure from 3 R per mole of atoms is generally due to two factors: (1) failure of the higher quantum-energy-spaced vibration modes in gas molecules to be excited at room temperature, and (2) loss of potential energy degree of freedom for small gas molecules, simply because most of their atoms are not bonded maximally in space to ...

This list is sorted by boiling point of gases in ascending order, but can be sorted on different values. "sub" and "triple" refer to the sublimation point and the triple point, which are given in the case of a substance that sublimes at 1 atm; "dec" refers to decomposition. "~" means approximately.
A Century Aluminum plant in Kentucky vented tons of perfluorocarbons, or PFCs, which are among the most potent and longest-lasting greenhouse gases on the planet.
The thermal grease 860 is a silicone oil with a Zinc Oxide filler and 8616 and 8617 are synthetic oils with various fillers including Aluminum Oxide and Boron Nitride. At 25 °C the densities are 2.40, 2.69 and 1.96 g/mL for the greases 860, 8616 and 8617 respectively.
Aluminum can prices vary by region and are based on weight. The average recycling value per pound of cans in the U.S. is currently $0.56. How many aluminum cans are in a pound?
All values refer to 25 °C and to the thermodynamically stable standard state at that temperature unless noted. Values from CRC refer to "100 kPa (1 bar or 0.987 standard atmospheres)".
